European Commission brings UK gas day into line
The UK is having to bring its ‘gas day’ into line with continental Europe, so that all gas grids are synchronised
UK shippers lobbied to retain their gas day, arguing that UK-continent pipeline operators can use linepack to compensate for the different entry-exit times between grids.
Both gas days start at 6am local time, but the UK is an hour behind.
Shippers thought that the cost of changing all the meters at the terminals – necessary for the claims validation process – would be expensive while not changing them would leave them exposed to imbalance charges.
However the change was put in place by the Agency for the Cooperation of Energy Regulators, which answers to the European Commission, which wants network codes to fit in with each other. Amending continental network codes is difficult as they count as primary legislation and override the UK network code.
The EC wanted a single network code governing balancing, congestion management and capacity allocations, for all of which processes the definition of the gas day is fundamental. The UK launched its network code in the late 90s and now shippers are devising a work-around to solve their problem.
